This project uses the black code style with 88-character line lengths for code and docstrings. It is recommended to use ruff for both linting and formatting and the pyproject.toml file contains the appropriate configuration. For Visual Studio Code, the following project file is compatible with the project configuration:
{
"[python]": {
"editor.formatOnSave": true,
"editor.codeActionsOnSave": {
"source.fixAll": "explicit",
"source.organizeImports.ruff": "explicit"
},
"editor.wordWrap": "off",
"editor.tabSize": 4,
"editor.defaultFormatter": "charliermarsh.ruff"
},
"[markdown]": {
"editor.wordWrapColumn": 88
},
"[restructuredtext]": {
"editor.wordWrapColumn": 88
},
"[json]": {
"editor.quickSuggestions": {
"strings": true
},
"editor.suggest.insertMode": "replace",
"editor.formatOnSave": true,
"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.tabSize": 2
},
"[yaml]": {
"editor.insertSpaces": true,
